Specification of Letters Patent.

Patented June 8, 1915.

Application filed April 11, 1914. SeriaLNo. 831,112.

which thefollowing is a specification.

The magazines of a typographical compos ing 1V and distributing machine of the type known under the trade mark Linotype occupy an oblique position in the machine, sloping downward and frontward from their so-called magazine entrances through which the distributed matrices are returned 1nto the magazines by the distributer, to their delivery mouths through which the matrices pass into theso-called assembler entrance. .All the matrices of the same character are kept distinct from those of the other charby being one behind the other 1n their own channel; the obliquity of the magazines providing .thatjthey shall slide down their respectlve channels toward. and-through the delivery month by gravity. Consequently,

the-front matrix in any channel is always close up to the respective delivery mouth, the remainder standing in close order behind and touching the respective one in front. 'A larger quantity of some characters is necessary than of others Consequently some channels are full while others may be only a third full.

There are two directions in which a magazine can be taken off the machine for another to be substituted for itone is downward and frontward and the other is rearward. In a frontward substitution, the delivery mouths of both magazines concerned, are lower than thelr magazine entrances throughout it, so that there is no motion on the part of the matrices in the said magazines independent of the respective magazine. But a rearward substitution necessitates the magazine being tipped in such a way that its magazine entrance is for a time lower than its delivery mouth, the consequence being that all the matrices in a partly empty channel would then slide down the latter up to the usual magazine-entrancecloser and'be damaged more or less by the sudden stoppage The substituted magazine would'be' subjected to a like tipping, so that two fonts of matriceswould be damaged at each substitution.

I Throughout this specification and claims, the terms matrix, matrices are to be read as including the respective alternatives type die, type dies.

The present invention consists in automatic means for locking the matrices in the partially full channels of a magazine being taken off its machine rearward, against sliding down their channels up to the magazine-entrance-closer and for unlocking the.

correspondingly circumstanced matrices in the substitute magazine as it is being substituted. These means are located partly in;

each'magazine and partly on the frame of the machine.

Theaccompanying drawings illustrate a preferred constructional form of the application of the invention to a machine of the above mentioned type.

Figure 1 is a side elevation from the right hand of the machine; Fig. 2, a detail sectional side elevation through part of a matrix-channel; Figs. 3 and 4: are detail plans respectively of the unlocked and locked positions; and Fig. 5, a plan of a magazine in the respective position.

1 is a magazine having the usual matrices 2 in its matrix channels 3 and supported upon a so called magazine frame 4 pivoted by a transverse pivot 5 in or on the machine frame 6 so that it can be tipped for a substitution, the magazine being held on its frame 4 sothat its channels 3 shall always register with the respective channels of the magazine entrance 7 and assembler entrance 8, by the engagement of a front-to-rear cen tral bar 9 on its bottom face, in a corresponding groove 10 in the top of its frame 4, as heretofore.

1lFigs. 2 to 5 is a transverse bar having its top face flush with the top face of themagazinebottom plate 12 and therefore blocking the channels '3 but for the channels 16 described farther on, its sides 13 engaged stitution and when so projectingfrom that side, holding channels 16 in the said top face of the bar 11, in register with the matrix channels 3 in the top face of the plate12, and its opposite end 17 not pro- .jectingifar enough beyond the respective side of the magazine 1, to come into contact with the machine frame 6 as that magazine is being drawn rearward. This is the composing position and the matrices 2 slide down their channels in the usual way. As the said magazine is drawn rearward and before it and its frame 4: have been tipped downward beyond the horizontal, the end 14 engages the cam face 15 whichforces the bar 11 across the magazine, thereby blocking the channels 3, and locking the matrices lying between it and the magazine delivery mouth closer and, further making its opposite end 17 project beyond the respective magazine-side as much as the end 14: had been projecting beyond its side. When the samefmagazine comes to be substituted, its

bar-end 17 will engage with the cam face 18 on the respective side of the machine frame 6 and be pushed by it back again across the magazine, thereby unblocking the channels 3 by making the channels 16 register with them and consequently unlocking the matrices between it and the magazine entrance mouth closer.

I A bar 11 is positioned in a magazine just to the rear of the columns of matrices which it is to lock and unlock. And as (as it has been pointed out) the columns vary in length, some being a third, others a half, and others say two thirds of the length of a channel 3, there may be a bar for each short length. Fig. 5 has assumed that there are two short lengths in the magazine.

In both cases, the matrices then between a bar 11 and the magazine delivery mouth closer are locked against sliding down the position as the magazine is removed from the typographical composing machine consistalways one end projecting to engage with a stationary cam face to slide the engaging bar farenough across the magazine-plate to block its matrix channels as that magazineis-bein'g taken off the machine, and to project the other end far enough to engage with another stationary cam face as the same magazineis being substituted for a predecessor, to make the channels in the bar register again with the said matrix channels.

a. In a typographical machine, the combination of a supporting frame mounted to swing'downwardly from its normal position in the machine, a magazine for the type or matrices arrangedon the supporting frame and removable at will therefrom, locking means carried by themagazine for preventing the escape of the type or matrices therefrom, and automatic mechanism for rendering said locking means active during the removal of the magazine from its supporting frame. a

5. In a'typographical machine, the combination of a supporting frame mounted to swing. downwardly from its normal position in the machine, a magazine for the type or matrices arranged on the supporting frame and removable at Wlll therefrom,

locking means carried by the magazine for preventing the escape of the type or matrices therefrom, and automatic mechanism for rendering said locking means active and inactive as the magazine is removed from and replaced on its supporting frame, respectively.

6. In a typographical machine, the combination of a supporting frame mounted to swing downwardly 'from its normal position in the machine, a magazine for the type or matrices arranged on the supporting frame and removable at will therefrom, locking means carried by the magazine substantially mldway between its ends so as to engage within the partially filled channels and pre- "vent the rearward shifting of the type or matrices therein, and automatic mechanism for rendering said means active during the removal of the magazine from its supporting frame.

'7. In a typographical'machine, the combination of a magazine formed with a series of grooves for the type or matrices and movable at will from its operative position, a movableplate or member formed with a corresponding series of grooves, and automatic means for moving said: plate laterally as the magazine is moved from itsoperative position in order to shift the. grooves in said parts out of registry.

8. In a typographical machine, the com-e bination of a magazine formed with a series of grooves for the type or matrices, and movable at will from its operative position, a movable plate or member formed with a corresponding series of grooves, and automatic means for moving said plate laterally to shift its grooves into and out of registry with those in the magazine as the latter is moved to and from its operative position.

9. A magazine for typographical machines containing a plurality of columns of type or matrices of different lengths, and pro- Gopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
